Spokesman of the Coalition of United Political Parties (CUPP), Ikenga Ugochinyere, has been released from police detention.
Mr Ugochinyere was released on Monday following a court order.
The CUPP spokesman was arrested last Thursday after a resolution passed by the House of Representatives.
He had accused the leadership of the House of collecting $10 million bribe from the Bill Gates Foundation to pass the Infectious Disease Control Bill.
However, Justice Musa Ottoman of the Federal Capital Territory High Court in Abuja granted his release following an ex-parte motion filed and dated June 9 by his lawyer, Chibuzor Ezike.
The court also restrained the police from arresting him after meeting his bail conditions of N200,000 with a surety who must not be less than level 8 officer.
“In the name of the President of the Federal Republic of Nigeria, directing the 5th defendant (police) or any officer under his control or command to release the applicant, Ikenga Imo Ugochinyere forthwith and unconditionally from unlawful and illegal detention, a product of disobedience of a lawful and subsisting order of the court,” the judge ruled.
The trial was adjourned till July 16.
